Primary: Oklahoma has a closed primary system, in which the selection of a party's candidates in an election is limited to registered party members.

Voter registration: Voters had to register to vote in the primary June 1. For the August 28 runoff, the voter registration deadline was August 3. For the general election, the voter registration deadline is October 12.[1]

Sullivan was defeated by challenger Jim Bridenstine in the GOP primary.[3] The day of the primary, Sullivan said he had made a mistake by ignoring the primary challenge for too long. "I never had a race like this in all my life," he said.[4]

This is the 3rd congressional district prior to the 2010 redistricting.

District partisanship

FairVote's Monopoly Politics 2012 study

In 2012, FairVote did a study on partisanship in the congressional districts, giving each a percentage ranking (D/R) based on the new 2012 maps and comparing that to the old 2010 maps. Oklahoma's 1st District did not become more Republican or Democratic because of redistricting.[11]

2012: 32D / 68R

2010: 32D / 68R

Cook Political Report's PVI

In 2012, Cook Political Report released its updated figures on the Partisan Voter Index, which measures each congressional district's partisanship relative to the rest of the country. Oklahoma's 1st congressional district has a PVI of R + 16, which is the 39th most Republican district in the country. In 2008, this district was won by John McCain (R), 64-36 percent over Barack Obama (D). In 2004, George W. Bush (R) won the district 65-35 percent over John Kerry (D).[12]
